Quoted from KevyMetal:I had the over current error on a spike system. I replaced my coin door and I found 2 incandescent bulbs in the coin returns. Removed them and no more error. Must be the old school lamps were pulling too much current. All my other Spike sterns have leds in the door
. No issues.
Never use incandescent bulbs with the spike system, they draw too much current and will trigger overcurrent protection.
